This invention relates to a pin and bushing removing tool and especiallyto a device of this character which is particularly intended for usein'removing king pins and their bushings fromthe front axles ofautomobiles but it is understood, of course, that a tool inaccordancewith this invention may be used for any purpose and in any manner forwhich thesame may be found adapted.

lo and desirable.

An important object of the invention is to provide, in a mannerashereinafter set forth, a tool of the character described embodying anovel construction and arrangement of parts whereby said tool may beexpeditiously adjusted for use on the different axles which may be foundin various makes of automobiles.

@ther objects of the invention are to provide a pin and bushingremovingtool of the character set forth which will be simple inconstruction, strong, durable, efficient and reliable in use and whichmay be manufactured at low cost. I All of the foregoing and stillfurther ob jects and advantages of the invention will become apparentfrom a study of the following specification, taken in connection withthe ac companying drawings wherein like charac- 39 ters of referencedesignate corresponding parts throughout the several views, and

wherein Figure 1 1s a view principally in side elevas tion and partlybroken away in vertical longitudinal section showing a tool inaccordance with this invention mounted in operative position on anangle.

Figure 2 is a view in vertical section through the axle takensubstantiallv on the line 2-2 of Figure 1 looking in the directionindicated by the "arrows and showing the tool in end elevation.

Referring now in detail to the drawings, it will be seen that thereference numeral 1 designates a beam having-a ratchet bar 2 disposedfor vertical sliding movement through one end portion thereof, saidratchet bar having a yoke 3 on its upper end for engagement with theaxle 4. A keeper 5 is slidably mounted on the beam 1 and is yieldingly1931. Serial No. 530,675.

It is believed that the many advantages of a pin and bushing removingtool constructed in accordance with this invention will be readilyunderstood, and although the preferred embodiment of the invention is asillustrated and described, it is to be understood that changes indetails of construction may be had in the combination and arrangement ofparts which will fall within the scope of the invention as claimed.

What is claims is 1. A pin and bushing removing tool comprising asupporting hanger including a pair of spaced, parallel bars fordisposition on opposite sides of a support, removable pins extendingbetween the end portions of the bars, a fixed pin extending betweenintermediate portions of the bars, substantially conical pairs ofrollers journaled on the first named pins, between the bars, the rollersconstituting each pair having their small ends disposed adjacent eachother, the rollers on the uppermost pin being adapted for rollingcontact with the support, a beam slidable between the bars on thelowermost rollers, a jack screw threaded through one end portion of thebeam for engagement with the pins and bushings, and means adjustablymounted on the other end portion of the beam and engageable with thesupport in a manner to retain the beam against swinging movement on thelower rollers when the jack screw is actuated.

2. A pin and bushing removing tool comprising a beam, means for mountingsaid beam on a support, said means including a pair of spaced, parallelbars extending on opposite sides of the support and the beam, pins exedon one end portion of the beam, and means on the other end portion ofthe beam en ageable with the support for retaining the am againstswinging movement when the jack screw is actuated.

In testimony whereof I afiix my signature.

tending between the bars above and below the support and the beamrespectively, said bars being slidable on the pins, rollers journaled onthe pins and engageable with the upper side of the support and the lowerside of the beam, a clamping screw extending through intermediateportions of the bars for clamping said bars against the support and thebeam, a ack screw threaded through one end 7 portion of the beam foroperative engagement with the pin or bushing to be removed, and means onthe other end portion of the beam engageable with the support in amanner to prevent swinging movement of the beam toward said support.

3. A pin and bushing removing tool comprising a hanger including a pairof bars, a roller journaled transversely between the bars for rollingcontact with a support, another roller journaled transversely betweenthe bars in spaced relation to the first named roller, a beam operablebetween the bars on the second named roller, a jack screw operativelymount-
